Abstract
A method of processing a silver halide photographic light-sensitive material by use of an automatic processor is disclosed, comprising the steps of developing an exposed photographic material with a developer, fixing with a fixer, washing and drying, wherein a swell ration of overall hydrophilic colloid layers including a silver halide emulsion layer and a protective layer provided on one side of a support is not more than 150%; and the developer, which contains substantially no dihydroxybenzene compound comprises a compound represented by the following formulas in combination with a 3-pyrazolidone compound or an aminophenol compound, and a carbonate salt in an amount of 0.35 mol/l or more.
Claims18
A method of processing a black and white silver halide photographic light-sensitive material and reducing silver sludge staining, said photographic material comprising a support having on one side thereof hydrophilic colloid layers including a silver halide emulsion layer and a protective layer, by use of an automatic processor comprising developing an exposed photographic material with a developer, fixing with a fixer, washing and drying, wherein:
- (a) the hydrophilic colloid layers have a degree of swell of not more than 150%, said degree of swell being determined as follows:
- Degree of swell (%)=(d-d.sub.0).div.d.sub.0 .times.100
- wherein d.sub.0 is a total thickness of hydrophilic colloid layers and d is a thickness of the hydrophilic colloid layers after having been dipped in distilled water at 25.degree. C. over a period of one minute;
- (b) said developer contains a compound represented by formula A-a! in combination with a 3-pyrazolidone compound or an aminophenol compound, said developer further containing a carbonate salt in an amount of 0.35 mol/1 or more and being substantially free from dihydroxybenzene compounds, formula A-a! ##STR44## wherein R.sub.3 represents a hydrogen atom, an alkyl, aryl, amino or alkoxy group, each of which may be substituted, a sulfo group, a carboxy group, an amide group, or a sulfonamide group;
- Y.sub.1 represents a sulfur or oxygen atom;
- Y.sub.2 represents a sulfur or oxygen atom, or NR.sub.4, in which R.sub.4 represents an alkyl or aryl group, each of which may be substituted;
- and
- (c) said developer is replenished by a developer-replenisher wherein said developer-replenisher is replenished at a rate of not more than 300 ml per m.sup.2 of a photographic material.
A method for processing a black and white silver halide photographic light-sensitive material using an automatic processor wherein the light-sensitive material comprises a support having on one side thereof hydrophilic colloidal layers which include a silver halide emulsion layer and a protective layer and wherein the automatic processor subjects the photographic material to developing with a developer solution, fixing with a fixer, and washing and drying, the improvement wherein:
- (a) said hydrophilic colloidal layers on said light-sensitive material has a degree of swell of not more than 150%, said degree of swell being determined as follows:
- Degree of swell (%)=(d-d.sub.0).div.d.sub.0 .times.100
- wherein d.sub.0 is a total thickness of hydrophilic colloid layers and d is a thickness of the hydrophilic colloid layers after having been dipped in distilled water at 25.degree. C. over a period of one minute;
- (b) said developer solution comprises
- (b1) an absorbic acid-like compound represented by formula A-a! ##STR46## wherein R.sub.3 represents a hydrogen atom, an alkyl, aryl, amino or alkoxy group, each of which may be substituted, a sulfo group, a carboxy group, an amide group, or a sulfonamide group;
- Y.sub.1 represents a sulfur or oxygen atom;
- Y.sub.2 represents a sulfur or oxygen atom, or NR.sub.4, in which R.sub.4 represents an alkyl or aryl group, each of which may be substituted;
- (b2) an auxiliary developing agent which is either a 3-pyrazolidone compound or an aminophenol compound;
- (b3) a carbonate salt in an amount of 0.35 mol/l or more;
- and
- (b4) substantially no dihydroxybenzene compound;
- and
- (c) said developer is replenished by a developer-replenisher wherein said developer-replenisher is replenished at a rate of not more than 300 ml per m.sup.2 of a photographic material.
